    About the FORMULA B Super Plexi

    If you hadn't guessed it already, the Formula B Super Plexi is based on the Marshall JTM45 "Plexi", with an additional Boost channel thrown in for good measure, capturing the sound of many legendary players from the 1960s onwards.

    Super Plexi Effects Order

    The Super Plexi V uses a rare Fairchild J201 MOSFET for beautifully warm, responsive tube-like tone. Like the Formula B Fuzz Rangers, there's a toggle to set whether the Boost comes before or after, giving you extra control of your sound - and more options to set your tone on fire!


    The Boost channel on its own gives you plenty of gain to push your amp onto overdrive, but this pedal really comes alive when you partner it with the Plexi channel. Run the Boost before the Plexi for lovely saturation and density; run the Boost after the Plexi to increase the volume and gun your amp's power tubes.

      Just what I was after.

      This is a fantastic drive pedal. There’s plenty of Plexi style pedals out there and I’ve owned a few, this one stood out for the switchable A/B-B/A switch. The boost side is nice and simple, much like an LPB-1. Not overly clean but a perfect partner to the drive side. The Plexi side is again nothing revolutionary but very good all the same and sounds great, on a par with far more expensive pedals.

      The build quality is also top end, very neat and tidy. Squeezed into the single enclosure and with a lifetime warrantee I couldn’t ask for more. I don’t think this’ll be leaving my pedal board any time soon!
